EP16-S35 Valve

SYMBOL:
EP16-S35 Valve symbol

DESCRIPTION
A spool-type, screw-in, cartridge-style, directional element, with multi-function
potential when used with other directional, pressure, or flow control devices. Can be
used as a pressure regulator for diesel engine applications including variable flow pump
controls, fuel and oil controls, SCR/EGR and exhaust controls and transmission controls. .

OPERATION
The EP16-S35 is a spring-biased blocking valve which will shift to allow full
flow from 1 to 2 only when pressure at 1 exceeds the cumulative pressure of 3,
plus the bias spring pressure value.
EP16-S35 is a pilot-to-close directional valve. With no pressure at 3, flow will
be allowed from 1 to 2 once the bias spring force is overcome with pressure at 1.
It requires a tall cap when specified with bias springs from 6,2 to 16,5 bar
(90 to 240 psi). The 240 psi spring reequires an extra tall cap. A manual override
option is also available for the valves with bias springs from 6,2 to 16,5 bar (90-240 psi).
Note: Orifice discs should not be used with this valve.

FEATURES
• Compatible with diesel fuel types 1 and 2.
• Corrosion-resistant plating.
• Stainless steel option - consult factory.
• Multiple function/application potential.
• Low pressure drop.
• Industry common cavity.
• Manual override available with 90, 110, 160, and 240 psi bias springs.
